I wouldn┬┤t trust clients to handle the failover. Would be better
to have two "floating" IP-addresses that each is sticking to a
different node in normal operation, but that can fail over to the other
node in failure or when you want to take one node out of production. Then
you do round-robin-dns over these two ip-addresses, and have a HA-LB

I used to use Heartbeat for such configurations also, but have recently
converted to using ucarp instead. It┬┤s *much* easier to use, and understand
than Heartbeat.
